Abstract

Articles, such as sanitary tissue products, including fibrous structures, and more particularly articles including fibrous structures having a plurality of fibrous elements wherein the article exhibits differential cellulose content throughout the thickness of the article and methods for making same are provided.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A fibrous structure comprising a paper web comprising a plurality of fibers and a coform fibrous structure comprising a plurality of filaments comprising a compostable polymer, wherein the plurality of filaments of the coform fibrous structure are spun onto the paper web such that the fibrous structure exhibits a CRT Rate of greater than 0.35 g/sec as measured according to the Absorptive Rate and Capacity (CRT) Test Method and a Wet Web-Web CoF of less than 1.85 as measured according to the Wet Web-Web CoF Test Method. 
     
     
       2. The fibrous structure according to  claim 1  wherein the compostable polymer comprises a thermoplastic polymer. 
     
     
       3. The fibrous structure according to  claim 2  wherein the thermoplastic polymer comprises a polyolefin. 
     
     
       4. The fibrous structure according to  claim 3  wherein the polyolefin is selected from the group consisting of: polypropylene, polyethylene, and mixtures thereof. 
     
     
       5. The fibrous structure according to  claim 1  wherein at least one of the plurality of fibers is a pulp fiber. 
     
     
       6. The fibrous structure according to  claim 1  wherein the fibrous structure further exhibits a Bending Modulus of less than 10.00 milligram·cm·grams/mils 3  as measured according to the Flexural Rigidity and Bending Modulus Test Method. 
     
     
       7. The fibrous structure according to  claim 1  wherein the fibrous structure further exhibits a TS7 of less than 17.0 dB V 2  rms as measured according to the Emtec Test Method. 
     
     
       8. A fibrous structure comprising a paper web and a plurality of fibers and filaments, wherein the plurality of filaments are spun onto the paper web such that the fibrous structure exhibits an HFS of greater than 17.0 g/g as measured according to the Horizontal Full Sheet (HFS) Test Method and a Wet Web-Web CoF of greater than 1.85 as measured according to the Wet Web-Web CoF Test Method. 
     
     
       9. The fibrous structure according to  claim 8  wherein at least one of the filaments comprises a polymer. 
     
     
       10. The fibrous structure according to  claim 9  wherein the polymer comprises a thermoplastic polymer. 
     
     
       11. The fibrous structure according to  claim 10  wherein the thermoplastic polymer comprises a polyolefin. 
     
     
       12. The fibrous structure according to  claim 8  wherein the fibrous structure comprises a coform fibrous structure. 
     
     
       13. The fibrous structure according to  claim 8  wherein at least one of the plurality of fibers is a pulp fiber. 
     
     
       14. The fibrous structure according to  claim 13  wherein the pulp fiber is a wood pulp fiber. 
     
     
       15. The fibrous structure according to  claim 8  wherein the fibrous structure further exhibits a Bending Modulus of less than 10.00 milligram·cm·grams/mils 3  as measured according to the Flexural Rigidity and Bending Modulus Test Method. 
     
     
       16. The fibrous structure according to  claim 8  wherein the fibrous structure further exhibits a TS7 of less than 17.0 dB V 2  rms as measured according to the Emtec Test Method.
